On October 15, we went to Brooklyn Historical Society and it gave me a new experience on doing research on map. From different type and different period of the map, I realize the maps can tell us a lot about the history, which we could not find on the reading. Such as the change on Pearl Street; and how a family view their neighborhood in their own family map. From the experiences in this semester, I learn a valuable lesson that things are not the same from different vantage points.  Because people have different point of view, even that was the same place, but we still see them differently by different time period. Such as the map of the 9^th Avenue on New Yorker magazine, his view of the world is different from what we see today, because the time and our thought are different with him. Thus, we should learn about the community by ourselves, analyzing the creditable resource and get to know what this community real likes. Brooklyn Historical Society is a great place to study the history, even we have internet, but there still have many material, resource that is not on the website. I think I will go back there when I need to research.
